I was having a hard time finding some Nankang CR-S (v.2) tires for my Porsche GT3RS. I ordered a couple of front tires from the FI Performance website (to go with some rears I found elsewhere). Not only did Brian promptly ship the tires he had, he located another set of fronts and 2 sets of rears, he gave me a good deal, and I had the extra tires waiting on my doorstep within a few days (in plenty of time for my HPDE event). Thanks FI Performance! Job well done.
